Polyether defoamers, as an important member of the defoamer field, contain many fascinating mysteries behind them.
The defoaming principle of polyether defoamers is based on their unique molecular structure. Its molecular chain contains hydrophilic ether bonds and hydrophobic alkyl chains. This special structure enables it to play an effective role in the foam system. It can quickly diffuse on the foam surface, reduce the surface tension of the foam film, and cause the foam film to rupture, thereby achieving the purpose of defoaming.
In the textile industry, polyether defoamers play a key role in the printing and dyeing and finishing processes. Due to the use of textile auxiliaries and mechanical stirring, a large amount of foam is easily generated. Polyether defoamers can quickly eliminate these foams, ensure the processing quality of textiles, and make them have better feel and appearance.
In the field of petrochemicals, polyether defoamers are also widely used in crude oil extraction, oil refining and other processes. In oil extraction, the circulation of drilling fluid will produce foam, affecting the extraction efficiency and safety. The addition of polyether defoamers can effectively solve this problem.
In sewage treatment, polyether defoamers also perform well. Surfactants and organic matter in sewage are prone to produce foam, which affects the treatment effect and equipment operation. Polyether defoamers can quickly eliminate these foams and improve the efficiency and quality of sewage treatment.
